To all'whom itmay concern:

Be it known that I-,-Lo1)ovroo BEOGARI, a subject of the King of Italy, and residing at Bologna, Italy, (whose post-ofiice address is Via Saragozza 22, Bologna, Italy,) have invented certain new and useful Improvements in Vials for the Conservation of Medicamental Liquids, of which the following is a specification.

This invention relates to improvements in the construction of glass vials for the conservation of medicaments to be used for hypodermic purposes.

It is well lmown that the hypodermic medication requires, as its essential condition, the most perfect sterility of the medicam'ental solutions.

This is obtained in part with the usual glass vials now extensively employed, but

such vials present numerous drawbacks due to the manner in which the same are broken to provide an outlet therein. The breaking of the neck of the device is not so easy as it may appear, and practice is required before a clean break can be assured, which is essential, especially to avoid finger wounds.

Furthermore, during the breaking operation, there is the possibility for the fingers to come into contact with the liquid, thus destroying its perfect sterility and consequently the chief purpose of the vial.

The object of the present invention is in the elimination of the disadvantages stated above. This is attained by establishing in the vial neck a point of less resistance, in

' which the breaking shall necessarily take place; also that the breaking of the glass neck may occur easily without the risk of shattering the entire vial.

Obviously, by the construction of a lass vial possessing a predetermined brea 'ng point in the neck there will be no danger of ones hands coming in contact with the break.

A vial in accordance with the present invention, and embodying the advantages stated, is illustrated by the accompanymg drawings in which: Figure 1 is an enlarged view 1n sectlon of the neck and upper portion of a glass vial.

Fig. 2 is a view showing the manner in which the vial is held prior to breaking the neck portion from the body. Fig. 3 1s a similar view to that of Fig. 2 showing the Specification of Letters Patent. Patented Ju ie 21, 1921 Abplication filed July 18, 1919. Serial No. 311,876;

neck portion having been broken away from the main body of the vial.

"Thevial, of c0urse,-1nay-be of any form and size, formed from a body of thin glass, and having a reduced portion or neck which may be easily broken at a determined point, which may be the most suitable for the drawing out of the contents means of a syringe, thus preventing the danger of the vial brea 'ng into ones hands.

Furthermore the breaking point is located at a considerable distance from where the vial is held which eliminates the danger of the fingers coming into contact with the liquid contents.

Referring to Fig. 1 of the drawing the main body A of the vial is provided with a reduced neck portion B extending above the main body and bent substantiall at right angles to the axis of the body. X globular swelling C is blown in the neck at a point beyond the elbow. The extended portion of the neck beyond the swelling C is closed by pointed portion D which serves to seal the vial. The enlarged portion of the neck retains any of the contents of the vial that may be in the neck when it is broken. This enlarged breaking of the bottle neck at a definite place when the bottle is to be opened.

Originally the neck B, when making the vial is straight, but it is then bent to about 90 by heating it. Now as the glass thickness is uniform, when the tube or neck B is bent, to the vertex of the angle formed,

there occurs a variatl n of the thickness, viz: the wall E forming the inner side of the elbow becomes thicker, while the. outside wall F becomes thinner. The outer wall of the elbow, because of the drawing of the glass to stretch over a greater area following the heating and bending opera tion, originates a weak spot or a point of little resistance. If the bent portion of the neck is forced toward its straight or original position when cold, a breaking will take place at the vertex of the angle formed by the bending.

From the above description it is evident that for opening the vial the body A may be held with one hand, and with the other hand holding the portion D, and then forcing this portion upward, as indicated by the arrow, thus producing a breaking at the bending.

of the vial by portion also serves to insure the Having now particularlydescribed and having abody and a sealed neck, said neck ascertained the nature of my said invention being bent in the form of an elbow and hav- 15 and in What manner the same isvto be pering one wall of the elbow thinner than the formed, I'declare that What I claim is"? other part thereof, whereby the neck can 7 .1.
